ObjectiveTo explore the technique of hepatic artery reconstruction in complicated hilar cholangiocarcinoma surgery. MethodThe clinicopathologic data of 3 patients with complicated hilar cholangiocarcinoma with arterial invasion underwent hepatic artery reconstruction in the Department of Hepatopancreatobiliary Center of Beijing Tsinghua Changgung Hospital from March to July 2022 were retrospectively analyzed. ResultsAll 3 patients (case 1–3) were the males, aged 53, 68, and 56 years, respectively, and with hypertension or diabetes; the longitudinal diameters of the tumor were 3.5 cm, 3.0 cm, and 3.2 cm, respectively. All patients had the right hepatic artery invasion. Case 2 and 3 had the arterial stratification. The arterial defects after radical resection were 4.5 cm, 3 cm, and 3 cm, respectively. The right or right posterior hepatic artery was reconstructed by the autotransplantation of right gastroomental artery, the left hepatic artery, and the anterior superior pancreaticoduodenal artery, respectively. After operation, the reconstructed hepatic arteries were unobstructed and free of stenosis, and there were no complications such as bleeding, infection, and thrombosis by Doppler ultrasound and CT angiography. The results of postoperative pathological diagnosis were the hilar cholangiocarcinoma with arterial invasion, and all the incisal edges were negative. ConclusionFrom the preliminary results of 3 cases, it is safe, feasible, and effective to select proper autologous artery (matched in length and caliber) for reconstruction the defective invaded hepatic artery which resected together with hilar cholangiocarcinoma, but the technical difficulty is still relatively high.
Objective To examine the influence of hormonal fluctuations on the perioperative outcomes of patients undergoing congenital heart surgery. Methods We conducted a retrospective analysis of clinical data from fertile women diagnosed with congenital heart disease at the Guangdong Provincial People's Hospital, between January 1, 2015, and July 30, 2019. Initially, patients were categorized into groups based on serum progesterone levels: a low progesterone group (n=31) and a high progesterone group (n=153). Furthermore, based on serum estrogen levels, they were divided into a low estrogen group (n=10), a medium estrogen group (n=32), and a high estrogen group (n=118) for comparative analysis. A control group (n=24) consisted of patients who received progesterone injections before their menstrual period. Results We finally included 184 patients. The patients’ average age was 27.6±5.7 years, with 142 (77.17%) presenting with complex congenital heart conditions. There were statistically significant differences in total postoperative standard thoracic drainage volume and postoperative albumin level between the high and low progesterone groups (P<0.05), while other perioperative outcome indicators showed no statistical differences (P>0.05). Among the different serum estrogen level groups, there were statistically significant differences in postoperative blood urea nitrogen levels, total postoperative standard thoracic drainage volume, and hospital stay (P<0.05), while other perioperative outcome indicators showed no statistical differences (P>0.05). ConclusionConsidering the overall clinical significance, the physiological changes in sex hormone levels appear to have a negligible effect on the perioperative outcomes of fertile women with congenital heart disease.
ObjectiveTo investigate the perioperative efficacy and safety of all-port robotic lobectomy versus thoracoscopic lobectomy in stageⅠA non-small cell lung cancer. MethodsThe clinical data of patients with stageⅠA non-small cell lung cancer who underwent lobectomy with lymph node dissection performed by the same operator in our center from June 2019 to June 2022 were retrospectively analyzed. The patients were divided into a robotic group and a thoracoscopic group according to different procedures. We compared the relevant indexes such as operation time, intraoperative bleeding, number of lymph node dissection stations, number of lymph node dissection, postoperative tube time, postoperative hospitalization time, closed chest drainage volume, postoperative pain, postoperative complications and hospitalization cost between the two groups. ResultsThere were 83 patients in the robotic group, including 34 males and 49 females with a median age of 60.0 (53.0, 67.0) years, and 94 patients in the thoracoscopic group, including 36 males and 58 females with a median age of 60.5 (54.0, 65.3) years. There was no conversion to thoractomy or death in postoperative 90 days in both groups. No statistical difference was seen in the operation time, total postoperative drainage volume and postoperative complication rates between the two groups (P>0.05). Patients in the robotic group had less intraoperative bleeding (P<0.001), more lymph node dissection stations (P=0.002) and numbers (P=0.005), less postoperative pain (P=0.002), and shorter postoperative time with tubes (P=0.031) and hospital stay (P<0.001). However, the surgery was more expensive in the robotic group (P<0.001). ConclusionAll-port robotic surgery is safe and effective for patients with early-stage non-small cell lung cancer with less intraoperative bleeding, more lymph node dissection, less postoperative pain, and shorter hospital stay compared with the thoracoscopic surgery.
Objective To investigate the effect of common iliac vein allograft replacing the portal vein-superior mesenteric vein transition area invaded by pancreatic cancer. Methods The clinical data of a patient with pancreatic cancer admitted to the Beijing Tsinghua Changgung Hospital in December 2021 who underwent pancreaticoduodenectomy combined with common iliac vein allograft replacing the junction of portal vein, superior mesenteric vein and splenic vein were analyzed retrospectively. The patient was a 77-year-old man who complained of “epigastric pain for 1 month and pancreatic mass was found for 1 week”. After admission, the patient was diagnosed with pancreatic cancer through inspection, and then the surgery was required. Preoperative examination and intraoperative exploration confirmed that the junction of portal vein, superior mesenteric vein, and spleen vein was invaded by tumor. In addition, the length of the invaded vessels measured by preoperative 3D reconstruction image was 5.5 cm, and the distance between the broken end of portal vein and the broken end of superior mesenteric vein measured was 4.5 cm during the operation. After tumor and vessels were resected, vascular anastomosis could not be performed directly. After accurate evaluation, pancreaticoduodenectomy combined with common iliac vein allograft replacing the junction of portal vein, superior mesenteric vein and splenic vein was performed. The operative time was 11 h, and the intraoperative blood loss was 400 mL. After the operation, the routine treatment was performed in ICU and was transferred to the general ward on the 7th day. Postoperative laboratory tests were performed to monitor liver function changes routinely, and imaging examination were was performed to monitor portal venous system blood flow. Results Postoperative complications such as biliary fistula, pancreatic fistula, hemorrhage, infection and thrombosis were not occurred. Postoperative pathological diagnosis: pancreatic ductal adenocarcinoma, medium-low differentiation. Enhanced CT reexamination on the 2nd and 13th day after the operation showed that the blood flow at the junction of portal vein, superior mesenteric vein and splenic vein of the common iliac vein allograft was unobstructed, and there was no stenosis or thrombosis at each anastomosis. Conclusions The application of common iliac vein allograft replacing the portal vein-superior mesenteric vein transition area invaded by pancreatic cancer is safe and feasible. The short-term efficacy is satisfactory, and long-term prognosis remains to be further observed.
